The rate of electricity charge up to 20 units is Rs 3 per unit and Rs 7 per unit from 21 to 30 units. If a family paid the bill of Rs 166 with Rs 50 service charge, how many units of electricity was consumed in the month?
Answers
Answer:
28units consumed in month
Step-by-step explanation:
20unit=20×3=60rs
now service charge +60rs=110
similary total paid=166
now 166-110=56
and 56/7=8unit
since total unit=28unit

speed of the car have to be to complete the trip in 17 hours?
Answers
The speed of car must be 60mile/hour, so that the trip will complete in 17 hours.
What is speed?
The rate of change of position of an object in any direction is called speed.
How do you calculate speed when distance and time is given?
According to the given question
At a speed of 68 miles per hour, the trip will be complete in 15 hours.
⇒ Total distance covered in 15 hours = 68 × 15 = 1,020 miles
( because, distance = speed × time)
Therefore, the speed of car to complete the trip in 17 hours
=
Hence, the speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

1xl pieces can you get out if
you use all of them?
Answers
Answer:192
Step-by-step explanation:
Calculate the area l*w or s*s
Divide the two areas to get the number of 1*1 from 1 plywood then multiply by their number which is 6 here
4*8=32/1=32*6=192
Final answer:
You can get a total of 192 pieces of 1'x1' plywood from six 4'x8' pieces.
Explanation:
To find the total number of 1'x1' pieces that can be cut from the 4'x8' plywood pieces, we need to find the total area of plywood available and then divide it by the area of the desired pieces.
First, calculate the area of one piece of plywood: 4 feet x 8 feet = 32 square feet.
Since there are 6 pieces, the total area of plywood is 6 x 32 square feet = 192 square feet.
Since each 1'x1' piece has an area of 1 square foot, you can get 192 1'x1' piecesout of all the plywood.

is its density?
Answers
Answer:
≈0.0947 kg/m^3
Step-by-step explanation:
p = density
m = mass
v = volume
Formula for density :
p = m/v
We know the mass and volume, so we can simply substitute our values into the equation:
p = m/v
p = 1800kg / 19000 m^3
p = ≈0.0947 kg/m^3
